When I was new to cryptocurrency. I've already heard people talking about a new coin that can have a fair match with bitcoin. Luckily, I didn't believe those and instead did my research although I did my alt invested but didn't go as they have directed.
I was near into that trap and that's why I've learned that it's always bitcoin is the best crypto to invest.
Good idea
When you are new and do not know much about it then yes, it is correct to invest in the known coins or market movers like BTC, ETH etc which can give you returns once the upward moments happen. And, once you know and have good knowledge than can look for some other coins to invest which can grow multiple times in coming months.
